◆ InitializeObject()

void SymbolFileCTF::InitializeObject ( )

Initialize the SymbolFile object.

The SymbolFile object with the best set of abilities (detected in "uint32_t SymbolFile::GetAbilities()) will have this function called if it is chosen to parse an object file. More complete initialization can happen in this function which will get called prior to any other functions in the SymbolFile protocol.
